it sounds clattery on idle it's a CTS stage1 only done 2.5k what does anyone think what is making it do this,

 

THe input shaft of the gearbox.

Press the clutch down does this make it go away ?? ore get worse ??
Could be Clutch Release Bearing??

 

I have a slightly rattly gearbox when building up speed in 1st and 2nd, goes away when I press the clutch. I hope it aint nackered!

 

it stops when clutch is down

 

My 2k went like this, but it got worse when you revved it unless you had ur foot on the clutch.

What happens if you rev it foot on and off the clutch? That wud be the best way to diagnose a thrust/release bearing

 

Well It's not definitive - The Clutch release bearing i have known to:
1) Make a noise - then quiten with the pedal depressed
2) Be quiet but only make a noise when the clutch is depressed !!

But if the noise totally goes away with the pedal down then i would say it's more likely to be the release bearing than anything else !!

Did you fit a new clutch KIT when you had the gearbox done 2k or so ago ?? - ie a release bearing fitted ??

 

this is what happens

well the clutch that was on had loads of life left so left it on but did not replace the release bearing

 

more than likely going to be the clutch release bearing then, what a

 

Sounds about right to me !!
At least it's cheaper than a new gearbox !!
Good luck mate !!

 

Most people put noise from the gearbox down to a component near by like bearing or shaft etc..

Chances are that if you cam belt is a tad loose your gearbox will rattle.

 

Had a thrust bearing go on me, was exactly the same as you describe

Why's that? Just interested

 

mine was rebuilt completely and mine knocks very slightly but wen i but the clutch down it goes away dats on idle.

 

lhd drive turboAgain sounds like a bearing...and sort out your sig mate

 

do you have a paddle clutch by any chance...

I did.. and my stage 1 box also done this...

nothing to worry about

 

mine got a brand new bearing and clutch in it its only done bout 400 miles the gearbox and clutch

i wud sort my sig out but dont even no how dat pic got there
